BIOS firmware package in ZIP format for a Positivo BGH laptop identified as XC7660, built on the NS4SL01 motherboard at revision 1.3. The 5.01 MB archive should contain a flash image meant for the SPI BIOS chip. Technicians use such dumps to recover boards that do not boot or show a blank screen after corruption, writing the image with an external programmer such as a CH341A. Read and save the original chip contents first, confirm the board revision on the PCB matches, and check the image size equals the chip capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
